The manual referred to is "Microprocessor Applications Manual", published by
Motorola (printed by McGraw-Hill) in 1975.
Pages 5-12 to 5-40 describe the hardware and software for using an MC6800
processor to read UPC codes. Included are flowcharts, schematics, and a
software listing.
One could probably lift the code and port it more or less directly to a newer
processor like the HD63P01 (a 6801 compatible made by Hitachi [and one of my
favorite chips - why doesn't Motorola make one with a piggyback Eprom socket?])
We had a student design a bar-code reader using some of this information. Watch
out for parasitics in the analog section...
